How to validate s:fileUpload ?

Hi. In seam, I'm trying to validate a filename when it's selected in a s:fileUpload, before it's submitted.

I can get the method called on onchange(), but the value I've set (the fileName) is still undefined. Is there a way to do this?


In the UploadRules bean, I have getters & setters for these variables:

And the method that gets called when the filename is selected (before it's uploaded by clicking the submit button). Neither variable is set ... and there's my problem. Ideas?

It is sorta covered in the JavaRanch Style Guide.
